The gas mileage for a 1994 Chevy full-size van varied significantly depending on the engine, transmission, and driving conditions. There wasn't one single figure. You'll likely find figures ranging from
10 to 18 MPG (miles per gallon), with the lower end being more common for heavier loads or city driving and the higher end for highway driving with a lighter load and a more fuel-efficient engine (if it had one).
To get a more precise estimate, you would need to know the specific engine size (e.g., 4.3L V6, 5.0L V8, 5.7L V8, 7.4L V8) and transmission type (automatic or manual). Even then, individual vehicle condition and driving habits play a role.
